With defect management information 120 blotters in temporary defect management area 104 and 105.By the way, also defect management information 120 is recorded in definite defect management 106 and 107.Subsequently definite defect management 106/107 and the difference between the temporary defect management area 104/105 are described.
Next, defect management information 120 is described.Defect management information 120 is that record/playback apparatus 200 (with reference to figure 9) is carried out the information that defect management uses.When record data being recorded in 100 last times of CD or when from CD 100, reset out record data, record/playback apparatus 200 execution defect managements.In this embodiment, defect management is mainly following.When having such as cut, dust on the user data area that detects CD 100 108, or when wearing and tearing defective such, record data being write down with the position away from this defective, and simultaneously, will withdraw data and be recorded in spare area 109 or 110.In addition, also carry out following the operation: when the record data that are recorded on the user data area 108 are carried out the operation of playback time defect recognition position with a part as defect management; And from spare area 109 or 110, read the operation that is recorded at first or has been recorded in the record data on the defective locations.In order to carry out this defect management, record/playback apparatus 200 needs the position of defect recognition in user data area 108.Defect management information 120 is mainly used in the position of record/playback apparatus 200 with defect recognition.
Fig. 2 has provided the content of defect management information 120.As shown in Figure 2, information 121 is set is included within the defect management information 120 with defect list 122.
As shown in Figure 2, information 121 is set comprises: the start address of user data area 108; The end address of user data area 108; The size of inner spare area 109; The size of outer spare area 110; And out of Memory.
Fig. 3 has provided the content of defect list 122.As shown in Figure 3; On defect list 122, record be used for representing defective in the address of the position of user data area 108 (being designated hereinafter simply as " defective addresses "), be used for representing the address (being designated hereinafter simply as " standby address ") of record data record position of 109 or 110 in the spare area; And out of Memory.When having a plurality of defective in the user data area 108, a plurality of defective addresses and the standby address corresponding with these defectives are included in the defect list 122.
By the way, not only to the user data area 108 of CD 100 but also the whole record surface of CD 100 is carried out defect management.
Next, discussed in the record aspect of defect management information 120.Temporary defect management area 104/105 on the CD 100 and the defect management of confirming 106/107 are to be used for defect management information 120 is recorded in zone wherein.Yet temporary defect management area 104/105 and the defect management of confirming 106/107 are different aspect its position, size and the application target.Discuss especially in the face of the difference in these two zones down.
Fig. 4 has provided an example of such state in temporary defect management area 104 or 105 that defect management information 120 is recorded in.Temporary defect management area 104 and 105 is such zones, promptly is used for recording defect management information 120 being recorded in wherein, up to CD 100 finalization of quilt temporarily.Defect management information 120 is the essential information of defect management.For each CD, whether exist defective with and the position all different so that need and remain on each CD with defect management information 120 record.In this example, in the stage before finalization, defect management information 120 is write down and remains in the temporary defect management area 104 or 105 on the CD 100.
In addition; In an embodiment; As shown in Figure 4; Preferably twice repetition or redundant is recorded in defect management information 120 (by the way, because carry out twice repetition or redundant recording defect management information 120, so Fig. 4 shows four defect management informations 120 altogether) in temporary defect management area 104 or 105.This can safety recording defect management information 120 and it is reset.Even do not carry out twice but for example once or three times or repeatedly to the record of defect management information 120, so also can to defect management information 120 with withdraw data and carry out suitable record and playback.
Finally change up to CD 100, can upgrade several times to defect management information 120 in some cases.For example, dust is attached on the CD 100 between (promptly additional or record continuous or that add) if write down and write down for the second time in the first time, when writing down for the second time, detects defective (or dust) so.According to this detection, defect list 122 is upgraded.When having upgraded defect list 122, will comprise that so the additional record (promptly once writing) of the defect management information 120 that upgraded defect list 122 is in temporary defect management area 104 or 105.Therefore CD 100 is Write-once-type recording mediums, can not make to have upgraded defect management information 120 and cover on the existing defect management information 120.Therefore, as shown in Figure 4, after the existing defect management information 120 of being recorded in of defect management information 120 serials of upgrading.Therefore, in this case " effectively defect management information 120 " is illustrated in the additional for the second time defect management information 120 that writes.
In order to realize that this of defect management information 120 repeated and serial recording, temporary defect management area 104 and 105 is greater than the defect management of confirming 106 and 107.
In addition, as shown in Figure 4, preferably (continuous) with defect management information 120 serials is recorded in temporary defect management area 104 or 105.With regard to temporary defect management area 104 or 105, preferably confirm the record order of defect management information 120 in advance.
Especially in this embodiment, when having upgraded defect management information 120,, so also the distinctive information of logo area 111 is upgraded if the temporary defect management area that defect management information 120 will record has changed.That is to say, for example,, so the distinctive information of logo area 111 is upgraded if the free space of temporary defect management area 104 has been used up and subsequently defect management information 120 is recorded in the temporary defect management area 105.Therefore, the distinctive information of this moment is represented effective defect management information 120 is recorded in the temporary defect management area 105.Ad hoc structure to distinctive information carries out detailed description (referring to Fig. 7 or the like) subsequently.
Fig. 5 has provided an example of such state in definite defect management 106 or 107 that defect management information 120 is recorded in.The defect management of confirming 106 and 107 is such zones, and what the defect management information 120 when being about to CD 100 finalization was confirmed is recorded in wherein.In other words, in the stage before finalization, definite defect management 106 and 107 is Unrecorded (or blank).When CD 100 is finally changed, defect management information 120 is recorded in definite defect management 106 and 107, and should the record situation with continued.
In this example, as shown in Figure 5, preferably twice repetition or redundant defect management information 120 is recorded in definite defect management 106 or 107.This can safety recording defect management information 120 and it is carried out safe playback.Even do not carry out twice but for example carry out once or carry out three times or record repeatedly, so also can carry out suitable record and playback to defect management information 120.
According to the CD among this embodiment 100; Temporary defect management area 104 between Lead-In Area 101 and the spare area 109 and temporary defect management area 105 between spare area 110 and leading-out zone 103, this can provide the compatibility between Write-once optical disc 100 and the general CD-RW.But in order to realize the compatibility with general rewriting type optical disk; Write-once optical disc 100 must have Lead-In Area, spare area, user data area, spare area and leading-out zone, and must keep such as these regional orders, position and the such master record structure of size (size).Though CD 100 has temporary defect management area 104 and 105, CD 100 still keeps this master record structure, and this can provide compatible.In other words, if temporary defect management area 104 is in the Lead-In Area 101, so as stated because temporary defect management area 104 is relatively very big, therefore can only select to enlarge the size of Lead-In Area 101, this is very disadvantageous.Yet, in this example, this shortcoming can not appear, because temporary defect management area 104 is positioned at outside the Lead-In Area 101.In addition; If temporary defect management area 104 is among the user data area 108; The defect management information 120 that has the control information characteristic so will be included among the following user data area 108; Said user data area 108 is the zones that should record record data in it, and this can cause that control information and following record data are mingled in the shortcoming among the user data area 108, and said record data are the information that has with the control information different qualities.Yet, in this example, because temporary defect management area 104 is positioned at outside the user data area 108, therefore this shortcoming can not appear.So same for temporary defect management area 105.
Each start address of the start address of user data area 108 and end address and spare area 109 and 110 (or the size of user data area 108 and spare area 109 and 110 or the like) is included in (with reference to figure 2) among the information that is provided with 121 of defect management information 120.This is provided with information 121 and is provided with by record/playback apparatus 200.In other words, if each size of the start address of user data area 108 and end address and spare area 109 and 110 clearly is shown the information of setting 121, they can be allowed to change so.Even they change, but also can keep the compatibility with general rewriting type recording medium.Therefore, move (to outer circumferential sides) backward through the start address that makes user data area 108 and can guarantee the interval between Lead-In Area 101 and the user data area 108, and temporary defect management area 104 is located in this interval.According to the start address how user data area 108 is set, can keep or guarantee the temporary defect management area 104 of big relatively (large scale relatively).So same for temporary defect management area 105.
According to CD 100, the defect management of confirming 106 and 107 is in respectively in Lead-In Area 101 and the leading-out zone 103, and this can provide the compatibility between Write-once optical disc 100 and the general CD-RW.That is to say, but general rewriting type optical disk has the zone that is used for recording defect management information, these zones are among Lead-In Area and the leading-out zone.CD 100 also has the defect management of confirming 106 and 107 that lays respectively among Lead-In Area 101 and the leading-out zone 103.At this point, their interrecord structure is identical.Therefore, but can guarantee the compatibility between Write-once optical disc 100 and the general rewriting type optical disk.
By the way, in the above-described embodiments, be applied to information recording carrier of the present invention that such a case is an example on the single-layer optical disc.Yet, the present invention be not limited to this example and may be used on two-layer or multiplayer optical disk on.Fig. 6 has provided the example that information recording carrier of the present invention is applied to two-layer CD such a case.In the ground floor of the two-layer CD 150 in Fig. 6 (upside of Fig. 6); Identical with CD 100; There is Lead-In Area 151 on the inner circumferential side, and is arranged with temporary defect management area 154, spare area 159, user data area 158, spare area 160, temporary defect management area 155 and leading-out zone 153 in direction towards outer circumferential sides.Logo area 161 is arranged in the Lead-In Area 151.In the second layer; Identical with CD 100; There is Lead-In Area 171 on the inner circumferential side, and is arranged with temporary defect management area 174, spare area 179, user data area 178, spare area 180, temporary defect management area 175 and leading-out zone 173 in direction towards outer circumferential sides.
By the way; To with Fig. 6 in two-layer or explanation that multiplayer optical disk is relevant in; Show the identical such parallel track path of record direction of ground floor, but can adopt the opposite such opposite track path of record direction of ground floor with the second layer with the second layer.
Next, with reference to figure 7 and Fig. 8, the data structure of logo area is elaborated.Fig. 7 has provided the more detailed data structure of the logo area 161 in the two-layer CD 150.Fig. 8 A to Fig. 8 D has schematically provided particular example of one side of the record of its logo area 161 that changes according to the temporary defect management area of using.
As shown in Figure 7, there are three tag unit districts (162,163 and 164) in the logo area 161.Each size in these three tag unit districts is big or small corresponding with the zone of the error correcting code that is used for CD 100 (ECC) bunch.Not only can use the zone that is used for ECC bunch but also can use arbitrarily the zone as a token of to distinguish 161 tag unit district.
After this, according to the recording status of the data in these three tag unit districts, can illustrate effective defect management information 120 be recorded in temporary defect management area territory 154,155,174 and 175 which the district in.That is to say that all these three tag unit districts show the information corresponding with above-mentioned distinctive information.In this embodiment, be in recording status or be in not recording status according to each, these three tag unit districts 162,163 and 164 show the temporary defect management area that records effective defect management information 120 in it.
" recording status " expression dimple-shaped among this embodiment is formed in such state among the tag unit district, and pit can be represented the booking situation data or needn't represent the booking situation data.On the other hand, " not recording status " expression pit is not formed among the tag unit district and it has the recording layer such state corresponding with similar mirror plane,
By the way, preferably the number in tag unit district is only little by one than the number for the temporary defect management area that CD provided.That is to say, if exist n to be the temporary defect management area (n: integer, n >=2) that CD provided, the number in tag unit district preferably " n-1 " so.For example, under the situation of the CD 100 in Fig. 1, because there are two temporary defect management area, so the number in tag unit district is one.For example, as shown in Figure 7 under the situation of the CD 150 in Fig. 6, because there are four temporary defect management area, so preferably three of the numbers in tag unit district.
Next, with reference to figure 8A to Fig. 8 D, a particular example of the recording status of tag unit district 162,163 and 164 is described.
Shown in Fig. 8 A, if all tag unit districts 162,163 and 164 are in not recording status, this representes that for example temporary defect management area 154 is effective (promptly using) so.That is to say that this expression is recorded in effective defect management information 120 in the temporary defect management area 154.
Shown in Fig. 8 B, if tag unit district 162 is in recording status and tag unit district 163 and 164 is in not recording status, this representes that for example temporary defect management 155 is effective (promptly using) so.
Shown in Fig. 8 C, if tag unit district 162 and 163 is in recording status and tag unit district 164 is in not recording status, this representes that for example temporary defect management area 174 is effective (promptly using) so.
Shown in Fig. 8 D, if all tag unit districts 162,163 and 164 are in recording status, this representes that for example temporary defect management area 175 is effective (promptly using) so.
Therefore, for example,, can relatively easily search for the temporary defect management area that records effective defect management information 120 in it so if described subsequently record/playback apparatus is used for CD 150 (or 100) is reset.Therefore, can reduce the time span of wanting search for defects management information 120 required.Consequently, replay operations is quickened.
Even CD 150 is write-once types; So through write some information make in the logo area 161 according to the number of temporary defect management area pre-assignedly be in not that the tag unit district of recording status changes into the zone that is in recording status, also can distinctive information be written in the logo area 161 with the integrated mode of recording status not as recording status.Be set to be in recording status through the tag unit district as stated, can distinctive information suitably be recorded as logging mode and need not distinctive information is recorded another position once more.
The relevance of the temporary defect management area of using that tag unit district 162,163 and 164 recording status and these recording status are represented is not limited to shown in Figure 8.If recording status can be distinguished the temporary defect management area of using arbitrarily, can use recording status arbitrarily so.
By the way; In Fig. 7 and Fig. 8; Two-layer CD 150 is used to describe, even but at one deck CD 100 or other CDs and have under the situation of various recording mediums of two or more temporary defect management area, also can obtain the effect identical with CD of the present invention.

After this, CPU 361 defect management information 120 that will be stored in the DMI generator 360 is sent to rear end 400 (step S14).Defect management information 120 is stored in the defect management apparatus 477 of rear end 400.
After this, CPU 361 will be stored in defect management information 120 twice repetition or the redundant temporary defect management area that is recorded in CD 100 104 or 105 in the DMI generator 360 (step S15).In this case, preferably default appointment records the temporary defect management area of defect management information 120 in it in advance for the first time.
On the other hand, if (step S11: not), then whether finally CPU 361 does not judge CD 100 change (step S16) when CD 100 is not blank discs.Finalization is such processing, but promptly is used to arrange record format with the replay device through being used for general rewriting type optical disk and only be used for that the replay device of the general CD of play-back type comes CD 100 is reset.Can know through reference record control information in Lead-In Area 101 or the like whether CD 100 is finally changed.
(step S16: not), CPU 361 selects the temporary defect management area 104 or 105 (step S17) used so if CD 100 is finally changed yet.That is to say, select to comprise in it temporary defect management area 104 or 105 of effective defect management information 120.
Especially in this embodiment, when the temporary defect management area that step S17 selects to use, CPU 361 comes the temporary defect management area that records effective defect management information 120 in it is effectively detected and selects through witness marker district 111.Subsequently detailed description (referring to Figure 13) is carried out in this operation.
In addition, if a plurality of defect management information 120 is recorded in the temporary defect management area 104 or 105 that step S17 selects (referring to Fig. 4), CPU 361 selects and reads their central effective defect management informations 120 (step S18) so.That is to say that the stage before finalization when defect management information 120 is upgraded, then is recorded in defect management information 120 in temporary defect management area 104 or 105.A plurality of defect management informations 120 are pressed more new sequences serial arrangement.Therefore, in temporary defect management area 104 or 105, being positioned at terminal defect management information is effective defect management information.CPU 361 selects and reads the defect management information that is positioned at end.
Be positioned at terminal defect management information 120 (or last defect management information 120) in order to specify, this embodiment adopts following method.That is to say; Under the row of a plurality of defect management informations 120 continuous recording in temporary defect management area 104 or 105 situation; End address recorded information from the start address of temporary defect management area 104 or 105 to following zone; Record last defect management information 120 in the said zone, and zone subsequently is Unrecorded or blank.361 pairs of optical pickup apparatus 352 of CPU are controlled and from start address temporary defect management area 104 or 105 are swept.After this, the position of not writing down or space state began is detected and from this position temporary defect management area 104 or 105 oppositely swept.How Here it is specifies last defect management information 120.Through these class methods, can be easy to specify last or nearest defect management information 120 (being effective defect management information 120) and need not to utilize pointer or the like.
Effective defect management information 120 that CPU 361 will read is stored in the DMI generator 360 and with this information and is sent to rear end 400 (step S19).Effective defect management information 120 is stored in the defect management apparatus 477 of rear end 400.
On the other hand; If CD 100 be not blank discs but when finally changing (step S16: be); CPU 361 reads defect management information 120 (step S20) from the defect management of confirming 106 or 107 so, and this information is sent to rear end 400 (step S21).Defect management information 120 is stored in the defect management apparatus 477 of rear end 400.
As stated, produced defect management information 120, perhaps defect management information 120 selectively reads from temporary defect management area 104 or 105, and perhaps defect management information 120 is from the defect management of confirming 106 or 107, to read.After this, it is recorded in the DMI generator 360 of disk drives 300 and with it is stored in the defect management apparatus 477 of rear end 400.This has accomplished the preparation of defect management and has finished initial setting up.
Next, with reference to Figure 13 the operation of " temporary defect management area that selection is being used " among the step S17 of Figure 12 is elaborated.Figure 13 has provided the process flow diagram of this selection operation.By the way, for the purpose of the explanation, two-layer CD 150 shown in Figure 6 is used for explanation to replace CD 100 for ease.In addition, suppose that the distinctive information of the logo area 161 that distinctive information is represented is same as shown in Figure 8 with the relevance of the temporary defect management area of using, then carry out following explanation.
Shown in figure 13, CPU 361 reads the logo area 161 of CD 150 and the recording status (step S171) that reference is included in the tag unit district (referring to Fig. 7) within the logo area 161.
After this, the operation through CPU 361 comes judgement symbol cellular zone 162 whether to be in not recording status (step S172).
Consequently, be in not recording status (step S172: be), this means that so logo area 161 shows the recording status shown in Fig. 8 A if judge tag unit district 162.Therefore, CPU 361 is chosen as temporary defect management area 154 temporary defect management area of using (step S173).
On the other hand, be in not recording status (step S172: deny) if judge tag unit district 162, so after this whether judgement symbol cellular zone 163 is in not recording status (step S174).
Consequently, be in not recording status (step S174: be), this means that so logo area 161 shows the recording status shown in Fig. 8 B if judge tag unit district 163.Therefore, CPU 361 is chosen as temporary defect management area 155 temporary defect management area of using (step S175).
On the other hand, be in not recording status (step S174: deny) if judge tag unit district 163, so after this whether judgement symbol cellular zone 164 is in not recording status (step S176).
Consequently, be in not recording status (step S176: be), this means that so logo area 161 shows the recording status shown in Fig. 8 C if judge tag unit district 164.Therefore, CPU 361 is chosen as temporary defect management area 174 temporary defect management area of using (step S177).
On the other hand, be in not recording status (step S176: not), this means that so logo area 161 shows the recording status shown in Fig. 8 D if judge tag unit district 164.Therefore, CPU 361 is chosen as temporary defect management area 175 temporary defect management area of using (step S178).
Therefore, the temporary defect management area of can relatively easy and effective search using through witness marker district 161.That is to say, need carry out access and search for the temporary defect management area of using up hill and dale all temporary defect management area traditionally.Yet, according to this embodiment, as stated, needn't thoroughly search for it, the initial operation that loads (perhaps replay operations and recording operation) in the disc process is quickened.
Therefore especially, because logo area 161 is included among the Lead-In Area 151, when loaded disc 150, the temporary defect management area that can select to use is as the part of initial operation.Therefore, after this, can carry out normal playback or recording operation and do not have the selection that notes temporary defect management area.
Next, the recording operation to record/playback apparatus 200 describes.Figure 14 has mainly provided the recording operation of record/playback apparatus 200.Record/playback apparatus 200 is carried out record data is recorded in such recording operation in the user data area 108 of CD 100.Record/playback apparatus 200 is the executive logging operation when carrying out defect management.Record/playback apparatus 200 is carried out during recording operation and is checked and upgrade defect list 122 according to this checked result.CPU 361 through disk drives 300 has realized recording operation with the cooperation of the system controller 476 of rear end 400.
Shown in figure 14; Judge whether to have sent finalization or the record data of from CD 100, resetting out one the instruction after (step S31 and step S32); When the user had imported the instruction (step S33: be) that is used for opening entry, record/playback apparatus 200 responded this and record data is write down (step S34).Record data are recorded in each predetermined block.Record/playback apparatus 200 carries out record with reference to the defect management information in the defect management apparatus 477 that is stored in rear end 400 and to record data, carries out the defect management record according to this information simultaneously.
Record/playback apparatus 200 is carried out when piece of each record or when a series of write sequence of each end and is checked (step S35), and upgrades defect management information 120 according to checked result.The defect management information 120 that upgrade by the way, is the defect management information that is stored in the DMI generator 360 of disc driver 300.Specifically, when recognizing record data not by record owing to the result who checks (step S36: be), the record data that the CPU 361 of disk drives 300 will not write down are recorded in (step S37) in spare area 109 or 110.After this, CPU 361 estimates should to record above that on the position of record data and has defective, and will be used to represent that the defective addresses of this position and corresponding standby address are recorded in defect list 122 (step S38).Describe in the face of the operation that forms defective addresses and standby address down.
When with regard to a series of record data of record this moment, being through with above-mentioned steps S34 to S38 (step S39: be), CPU 361 is with defect management information 120 twice repetition upgraded or redundant being recorded in the temporary defect management area 104 or 105 on the CD 100 (step S40).
Therefore, defect management information 120 is recorded in the temporary defect management area of using, if but there is not free space (or not record space) in the temporary defect management area used, then it is recorded in another temporary defect management area.In addition, in this case, preferably simultaneously the tag unit district of logo area 111 is upgraded (be about in them at least one change into be in recording status).Carry out detailed description (referring to Figure 15) in the face of this recording operation down.
By the way, the defect management information 120 that is recorded in temporary defect management area 104 or 105 is the defect management informations 120 that are stored in the DMI generator 360.After this, recording operation is accomplished.
Next, with reference to Figure 15 additional or continuous among Figure 14 step S40 or recording of appending are carried out detailed explanation in the temporary defect management area.Figure 15 provided with defect management information 120 additional or continuous or append record the process flow diagram in temporary defect management area 104 or 105.
Shown in figure 15, at first, judge in it whether to have any free space (step S401) in temporary defect management area 104 or 105 of recording defect management information 120 through the operation of CPU 361.That is to say that judgement symbol district 111 (or 161) are represented will become whether to exist in the such zone of the temporary defect management area used and be used for further defect management information 120 being recorded in any free space wherein.
The result of this judgement is, has free space (step S401: be) if judge, and so defect management information 120 recorded in the current temporary defect management area of using (step S404).
On the other hand, there is not any free space (step S401: not), so defect management information 120 is recorded in the temporary defect management area of next using (step S402) if judge.For example; Under the situation of CD 100 (referring to Fig. 1); If temporary defect management area 104 is being used and is not being had a free space that is used for recording defect management information 120; Select temporary defect management area 105 with as the temporary defect management area of next using so, and defect management information 120 is recorded in the temporary defect management area 105.Perhaps; Under the situation of CD 150 (referring to Fig. 6); If temporary defect management area 154 is being used and do not had the free space that is used for recording defect management information 120, select in other temporary defect management area 155,174 and 175 any one with as the temporary defect management area of next using so.By the way, the temporary defect management area of next using can be predetermined, is perhaps for example selected by CPU 361 at the time point of step S402.
CPU 361 further can arrive data recording in the logo area 111 (161) (step S403).That is to say, can make at least one of recording status in the tag unit district that is provided for logo area 111 (161) become recording status.For example, suppose that on CD 150, temporary defect management area 154 is being used, and this moment, the operation through step S402 recorded defect management information 120 in the temporary defect management area 155.In this case, data are write down so that the tag unit district 162 of logo area 161 is in recording status.
Through this, if the temporary defect management area of during recording operation, using must change, can realize such logo area 111 (161) so, this logo area has its distinctive information that can reflect this variation.
By the way, if tag unit district 162 or the like is arranged to be in recording status, so not only through writing arbitrary data but also can forming pit through writing the booking situation data.For example, it is configured to write down and the tag unit district is arranged to be in recording status through the Backup Data to vital document.
Next, the finalize operation to record/playback apparatus 200 describes.Figure 16 has provided the finalize operation of record/playback apparatus 200.For example, shown in figure 16, when the user has imported the instruction that is used for finalization (the step S31 of Figure 14: be), record/playback apparatus 200 is confirmed CD 100 finally change yet (step S51: deny) and finalizing disc 100 (step S52).During finalization, record/playback apparatus 200 twice repetition or redundant defect management information 120 being recorded in the defect management of confirming 106 or 107 on the CD 100 (step S53).Can carry out once or repeatedly to the record of defect management information 120 for three times or.By the way, the defect management information 120 that is recorded in definite defect management 106 or 107 is the defect management informations that are stored in the DMI generator 360.After this, finalize operation is accomplished.
Next, the replay operations to record/playback apparatus 200 describes.Figure 17 has provided the replay operations of record/playback apparatus 200.
Shown in figure 17; When the user has imported the instruction (the step S32 among Figure 14: be) that begins to reset; Record/playback apparatus 200 confirms that CDs 100 are not blank discs (step S71: not), and to being recorded in record data in the user data area 108 on the CD 100 reset (step S72).200 pairs of record data of record/playback apparatus are reset, and carry out defect management according to the defect management information 120 in the defect management apparatus 477 that is stored in rear end 400 simultaneously.
As stated; According to record/playback apparatus 200; Before finalizing disc 100; Defect management information 120 is recorded in the temporary defect management area 104 or 105 of CD 100, and when finalizing disc 100, defect management information 120 is recorded in the defect management of confirming 106 or 107 on the CD 100.With regard to the CD 100 of finalization not yet, record/playback apparatus 200 reads defect management information 120 from the temporary defect management area 104 or 105 of CD 100.With regard to the CD 100 of finalization, record/playback apparatus 200 reads defect management information 120 from the defect management of confirming 106 or 107 of CD 100.With regard to the CD 100 of finalization not and with regard to the CD 100 of finalization, can realize the record of record data or reset, carry out suitable defect management simultaneously.
Especially, through logo area 111 (161) is provided, can be relatively easily and the temporary defect management area that effectively selection is being used from a plurality of temporary defect management area 104 and 105 (or 154,155,174 and 175).That is to say, can be relatively easily and effectively read effective defect management information 120.This can be reduced in the processing load of CPU 361 when loading disc or playback and record.
According to record/playback apparatus 200 of the present invention; It is configured in finalization process, defect management information 120 is recorded in the defect management of confirming 106 or 107 of CD 100, but this can make compatibility between Write-once optical disc 100 and the general rewriting type optical disk.
